Perpetual Motion Machine

[Kelnoen]

Firstly, I know perpetual is impossible, but I don't understand physics enough to disprove my own idea, can anyone shed any light?

Uses natural fixed magnets and magnetic shielding.
I'm not sure if the nature of magnetic fields allows them to flow around objects (rather than through objects).
Does anyone know if a magnetic field can be "clipped" or "masked" to make it finer?

Magnetic fields can be influenced by other materials or other magnetic fields... but I think they would cause a change in energy level... so the system will eventually decay.

Ah, so influencing the magnetic field through shielding will reduce the magnets "charge"?
That would make sense.

that system looks very much like LIM or LSM for roller coasters (linear induction motors, can't remember LSM, or the specific differences of the two).
How it works, is one set of magnets (the magnets on the coaster train) are natural rare earth magnets, while the magnets on the track are driven by AC current to switch polarization at a constant rate. This causes a pull/push motion that continues indefinitely (as long as there is power) so that the magnets never permanently attract.
That AC power is going to use power, but how much compared to what such a device can generate, I have no clue.

If you don't force one set of magnets to constantly change polarization, there will be no motion in the device as the magnets would become permanently attracted..

It's interesting. It seems that every perpetual motion idea I run across involves magnets. Odd that these are such a fundamentally misunderstood thing.

What will you use as magnetic shielding though? It will likely be magnetic itself. As it rotates past the North magnets on your diagram, the shielding itself will be attracted to the North magnets, causing drag, and slowing the rotor down. Rotor stops, machine is not perpetual.


I see only one way to make a perpetual motion machine, and it involves wormholes. Simplified, the exit is on the ceiling, and the entrance is on the floor. Drop a ball in the bottom, and it comes out the top. Put a paddlewheel in between. Falling ball turns the wheel, and continues to fall thanks to gravity.
Replace ball with a lot of water, and you've got yourself a nice-sized generator.
Only problem: creation of a stable wormhole.

The magnetic insulating material is Giron (0% Nickel 0 Magnetism, 0 Magnetic resonance).
The thing I'm confused about is whether the Magnetic field would refract around the tip of the shielding??

By that time you're going to have dilithium crystals and anti-matter reactors, so you won't care about the tiny amount of energy the wormhole generates. Maybe you can use a wormhole to power lower end devices like TriCorders.

there is a point of rotation where the force driving the opposite pole away is less than the force required to overcome the incoming repulsion. the system will stop when the difference of these energies is greater than or equal to zero. unless you proved an outside stimulus to overcome this barrier, it will stop almost immediately. u can spin it easily by controlling the current to the north poles cyclically, however that would defeat the purpose of the invention.

I have thought of building something similar a long time ago, but the positioning of the magnets cannot be symmetrical. I was thinking more of using more magnets and place them so that where one would finishes pushing off, the other ones would begin thus perpetually continues the cycle. One of these days I'll get to it.

It might turn a little bit with your design, but would get stuck (equilibrium state) if you don't input new energy into it .
